207--213

The purpose of this paper is to introduce new two classes of functions called ⍺-preirresolute functions and β-preirrsolute functions in topological spaces. Some properties and several characterizations of these types of functions are obtained. Also, we investigate the relationship between these clasess of functions and other classes of non-continuous functions.
